Book Description
Water is a key element in the survival of life on earth. Despite this importance, this valuable resource is being abused; either polluted or wasted. This thesis dealt with water wastage coming from agricultural use, i.e. irrigation. This wastage is the result of poor irrigation scheduling techniques, in addition to the use of inefficient water application systems. The aim of this study was to propose a dynamic, precise, and easy to use,GIS based irrigation scheduling model that could respond to different varying climatic conditions, improving water requirement computation precision. The model developed in this study consists of three parts; the first part involved reference evapotranspiration rate computationusing the FAO-Penman-Monteith CROPWAT software model. The second part dealt with actual crop evapotranspiration rate determination; this task involves correcting the reference evapotranspiration rate, which was determined in the first part. This correction is a function of crop type, stage of growth, in addition to soil parameters; according to the Nimah-Khalouf 1987 model. The third part involved schedule formulation based on the data determined in the preceding two parts. These three parts make up an irrigation scheduling model; this model was integrated into ESRI ArcMap, a GIS software. This integration adds a lot of functionality to the model; flexibility, updatability, ability to create a custom user interface which facilitates user interaction with the model, etc... The developed model was tested for functionality, in addition to responsiveness to climate variability taking Lebanon as a case study; it was found to be responsive to different scenarios of climate variability, fulfilling the objective of this study. Finally, this study resulted in the development of a GIS based irrigation scheduling model that could be further developed to be used in various applications: water requirement determination on regional and/or watershed level, another application would be irrigation requirement extension services, in addition to the ability of producing informative thematic maps.

Book Description
Software as a service (SaaS) is a primary working pattern and a significant application model for next generation Internet application. Web GIS services are the new generation of the Software as a service that can provide the hosted spatial data and GIS functionalities to the practical customized applications. This study focused on developing a webGIS based application, Soil Moisture-Based Irrigation Scheduling Tool (SMIST), for predicting soil moisture in the next seven days using the soil moisture diagnostic equation (SMDE) and the upcoming seven precipitation forecasts made by the National Weather Service (NWS), and ultimately producing an accurate irrigation schedule based on the predicted soil moisture. The SMIST is expected to be capable of improving the irrigation efficiency to protect groundwater resources in the Texas High Plains and reducing the cost of energy for pumping groundwater for irrigation, as an essential public concern in this area. The SMIST comprised an integration of web-based programs, a Hydrometeorological model, GIS, and geodatabase. It integrates two main web systems, the soil moisture estimating web application for irrigation scheduling based on the soil moisture diagnostic equation (SMDE), and an agricultural field delineation webGIS application to prepare input data and the model parameters. The SMIST takes advantage of the latest historical and forecasted precipitation data to predict soil moisture in the user-specified agricultural field(s). In this regard, the next seven days soil moisture versus the soil moisture threshold for normal growth would be presented in the result page of the SMIST to help users to adjust irrigation rate and sequence.

Book Description
The increasing risk of severe droughts and water shortages emphasizes the need for an integrated approach to drought mitigation. However, effective tools for the implementation of such an approach have not been available till now. This book contributes to an improved preparedness for drought in water supply systems, providing tools useful for a better decision making process in drought management. It presents methods and software features of a Decision Support System (DSS) developed within a European research project and consists of three main parts. The first part deals with the advanced techniques for hydrological drought identification and monitoring; the second analyses the successful use of climate-crop-soil models in defining deficit irrigation strategies; the third provides tools for improving the operation of irrigation supply reservoirs.
